1 Claim.

or both sides of the paper in one or more colors;

upon flat bed presses and also upon rotary presses. It has been found that where substances for preventing smutting or smudging are not applied to the top sheet on the impression cylinder that the said top sheet becomes soiled from ink brushed from the side of the sheet that has been freshly printed. When the top sheet becomes badly soiled the same must be replaced or smudging occurs. In the present type of smudge eliminating applicators, rollers are required for removing the substance from a suitable tank and applying the same to the impression cylinder. Such method has proven unsatisfactory and it is accordingly an object of the present invention to provide an apparatus for spraying the anti-smutting or anti-smudging substance directly to the impression cylinder to provide for the more even and better regulation of the application to the cylinder throughout its entire area.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawing forming part hereof, wherein like numerals refer to like parts throughout, and in which Figure 1 is a diagram of the spray apparatus, and

Figure 2 is an end elevational view showing the relative position of the spray nozzle with respect to the impression cylinder.

Referring now to the drawing in detail, the numeral 5 designates an air line leading from a compressed air tank (not shown) and to which is connected a branch pipe 6 leading to a fourway control valve 1. The control valve 1 is also connected to the pipe 5 beyond the branch 6 and in which is interposed a pressure regulating valve 8 to control the pressure of air leading from the pipe 5 to an oil supply tank 9.

From the tank 9 extends an oil supply line I!) leading to a battery of spray guns II and between each of the spray guns and the oil supply pipe I0 is interposed an individual control valve 12 and a check valve I3.

From the four-way control valve 1 the air line l4 extends, and to which are connected air feed lines l5 also leading to the respective spray guns II. In each of the air lines l5 are interposed control valves I6 to control the air supply to the individual spray guns.

The impression cylinder of the printing press is indicated at I! adjacent to which are positioned the spray guns H for spraying the antismutting substance directly against the side of the cylinder.

In Figure 2 of the drawing the impression cylinder is shown in operative relation with respect to the type cylinder 18, and between which the sheet of paper I9 is fed during the printing operation.

From the foregoing it Will be apparent that a suitable anti-smutting substance may be sprayed under pressure from the tank 9 to the impression cylinder and the proportion of the substance sprayed from the respective spray guns may be regulated by the individual control valves provided therefor.

It is believed the details of construction and manner of use of the invention will be readily understood from the foregoing without further explanation.

Having thus described the invention, what I claim is- In a device of the character described including a fluid supply tank, an air supply conduit connected to said tank, an air pressure regulator means interposed in said conduit in advance of said tank, an air ofitake pipe connected to said air supply conduit in advance of the regulator means, a fluid ofitake pipe connected to v said fluid supply tank, a plurality of nozzle means each having an air supply and a fluid supply branch pipe connected to said air offtake and fluid offtake pipes respectively, individual control valves in each of said air supply branch pipes and fluid supply branch pipes respectively, a checkvalve in each of said fluid supply branch pipes located between its respective control valve and nozzle means, and a four way valve connected'on two sides in said air ofitake pipe and on the two remaining sides in said air supply conduit between said regulator means and said tank whereby the air supply to the tank and the air ofitake pipe may be simultaneously controlled.
